Materials and Methods: Mice were randomly divided into 6 groups, with 6 mice per group; control, EVOO,CM, APAP, EVOO + APAP, CM +APAP. In APAP group, mice were treated with single dose acetaminophen (500mg/kg). Prophylactic groups were given EVOO and CM for 28 days before APAP administration, in the same dose as that of the toxic group. Liver enzymes, lipid profile, malondialdehyde (MDA) and total antioxidant (TAC) activities were assessed.

Result: In the toxicity group, increased concentrations of MDA and decreased TAC activities were found compared to the control groups (p < 0.05), with elevated liver enzymes. EVOO and CM treatment resulted in hepatoprotective effects as evident by a significant decrease in serum liver enzymes and liver malondialdehyde, with a synchronous increase in TAC compared to acetaminophen-treated group (p
